Insights

Rotavirus infection affects over 28% of young children with acute gastroenteritis in Marvdasht, Iran. Continuous surveillance is crucial for diarrhea prevention and informing rotavirus vaccine introduction strategies.

Area of Science:

  • Virology
  • Pediatrics
  • Public Health

Background:

  • Rotavirus is a leading cause of severe gastroenteritis in children globally.
  • Understanding regional rotavirus epidemiology and genotypes is vital for effective control strategies.

Purpose of the Study:

  • To determine the prevalence of rotavirus infection in children under five with acute gastroenteritis in Marvdasht, Iran.
  • To identify the circulating rotavirus genotypes in this population.

Main Methods:

  • Stool samples from 141 children (1 month-5 years) with severe diarrhea were analyzed.
  • Enzyme immunoassays (EIA) detected group A rotaviruses.
  • Nested RT-PCR was used for rotavirus genotyping.

Main Results:

  • Rotavirus was detected in 28.37% of children.
  • Infection peaked in summer and was most common in the first two years of life.
  • Mixed G genotypes predominated (60%), with G2, G4, and G1 also detected. G3/G8 mixed infection was reported for the first time in Iran.

Conclusions:

  • High rotavirus prevalence necessitates ongoing surveillance.
  • Monitoring new rotavirus strains is essential for public health policy and vaccine decisions.

Bacterial Gastroenteritis01:18

Bacterial Gastroenteritis

Bacterial gastroenteritis, characterized by diarrhea, abdominal cramps, and vomiting, is often caused by ingestion of contaminated food or water and is frequently associated with pathogenic Escherichia coli strains. These microbes exploit two principal mechanisms to inflict disease.Shiga toxin–producing E. coli, also referred to as STEC—notably O157:H7—release Shiga toxins that target ribosomes, blocking protein synthesis. The B subunit of the toxin binds the host glycolipid receptor...
Investigation of Disease Outbreaks01:23

Investigation of Disease Outbreaks

Multistate foodborne outbreaks pose significant public health risks and require meticulous investigation to identify sources and implement control measures. The Centers for Disease Control and Prevention (CDC) utilizes a dynamic seven-step process for these investigations, integrating data from laboratories, interviews, and environmental assessments to protect public health.Outbreak Detection: The detection of multistate outbreaks typically begins with PulseNet, the CDC's national laboratory...
Viruses of Archaea01:29

Viruses of Archaea

Archaeal viruses play a crucial role in the ecosystems of extremophilic archaea, particularly those belonging to the phyla Euryarchaeota and Crenarchaeota. By shaping host evolution and facilitating gene transfer, these viruses influence microbial communities and contribute to genetic diversity in extreme environments. The archaea they infect thrive in acidic hot springs and hydrothermal vents characterized by high temperatures and low pH. Archaeal viruses exhibit remarkable structural...

Size and Structure of Viral Genomes

Viral genomes exhibit remarkable diversity in size, structure, and composition, influencing their replication strategies and interactions with host cells. These genomes consist of either DNA or RNA and may be linear or circular. Additionally, they can be single-stranded or double-stranded, with each configuration affecting how the virus propagates within a host. RNA viruses, for instance, generally have smaller genomes than DNA viruses, a factor that contributes to their high mutation rates and...
Viral Hepatitis I: Introduction01:28

Viral Hepatitis I: Introduction

Viral hepatitis is an inflammatory condition of the liver caused by infection with hepatotropic viruses, most commonly hepatitis A, B, C, D, and E. Despite variations in structure and transmission, all viruses mentioned infect hepatocytes and provoke immune responses that can hinder liver function. Additionally, some non-hepatotropic viruses can also lead to hepatic inflammation.Hepatitis A VirusHepatitis A virus (HAV) is transmitted through the fecal–oral route, typically by ingestion of food...
